Problems solved by technology

[0003] At present, there are few water-based paints used for the interior of the cabin. The primer is generally made of paint, while the top coat is mainly water-based alkyd and water-based acrylic, and the water-based epoxy paint that combines the bottom and surface has not been reported.

example 1

[0020] Example one: A component (parts by weight):

[0021]

[0022] B component:

[0023] Waterborne epoxy curing agent 100

[0024] A: B = 100:12, the effective period of construction is 6 hours.

[0025] Process preparation method:

[0026] Add water, additive wetting and dispersing agent, defoamer I, defoamer II, and flash rust inhibitor into the stock pot in sequence, stir evenly at low speed, then add pigments and fillers, disperse at high speed for more than 20 minutes, and the grinding fineness is ≤40 Micron (beware of demulsification during the grinding process), then add fluorocarbon emulsion and flash rust inhibitor, stir well, add thickener to thicken, stir well, measure viscosity, if viscosity ≥ 50s (coat -4 cups, 25°C) It is qualified. If the viscosity is ≤50s, add an appropriate amount of thickener to thicken until the viscosity is ≥50s, then add defoamer II to defoam, stir evenly and then slowly add substrate wetting agent. The control speed should not ex...

Abstract

The invention discloses a water-based epoxy anti-corrosive coating and a preparation method thereof, and relates to a ship antirust and cabin inside and outside antirust fireproof paint. The invention provides a water-based epoxy coating with the VOC lower than 10g / l, and the coating belongs to an environment-friendly coating, which not only has the antirust performance of anti-corrosive coating, but also has low flame propagation of cabin inside finish paint, meets the requirement of cabin inside smoke and toxin, resists aging, and is a multifunctional water-based coating, and the bottom and the surface are combined. Zhejiang Ampang AB-EP-20 is used as the epoxy resin, Zhejiang Ampang AD-HGF is used as the curing agent, and fluorocarbon emulsion (the model of which is Beijing Baowei PF-1) is used as the base material. Wetting dispersant, defoamer I, defoamer II, flash rust inhibitor, thickener, defoamer and substrate wetting agent are used as additives, rutile titanium white powder, compound zinc phosphate, ferrotitanium powder, talcum powder, ultra-fine aluminum hydroxide, precipitated barium sulfate, mica powder and aluminum tripolyphosphate are used as pigment fillers.

Description

technical field [0001] The invention relates to a water-based epoxy anti-corrosion coating and a preparation method thereof, belonging to the fields of metal protection and flame retardancy, and in particular to anti-rust and fire-proof paints for ships, interiors and exteriors of cabins. Background technique [0002] At present, most of the anti-corrosion coatings in my country's submarines and various ship cabins use traditional solvent-based coatings, which contain heavy metal compounds such as chromium or lead, which are highly toxic and cause great harm to the marine environment and human health. The research and development of environmentally friendly water-based cabin coatings has very important practical significance for eliminating the hidden dangers of fire and poisoning incidents during the construction of interior cabin coatings and improving the living environment of interior cabins. [0003] At present, there are few water-based paints used for the interior of ...
